脳性麻痺児・者の図-地知覚能力の再評価

抄録

The purpose of this study was to make a non-manual figure-background perception test and to re-evaluate the previous researches on figure-background perception in cases of cerebral palsy. In study 1, 14 stimuli consisting of common, everyday objects embedded in a randomly arranged circle background were located on a distance scale by a pair comparison method. In study 2, seven proper stimuli were selected as test stimuli. In study 3, this test was applied to 30-80 months normal children, normal adults, and those of cerebral palsy. The major results revealed that sex, handedness, chronological age, IQ, pathological type of cerebral palsy and topographic type of cerebral palsy were not associated with the test scores. However, drawing ability was profoundly related to figure-background perception. Based on these results, the theories of figure-background perception were then discussed at length.
